I had made these as stocking stuffers last year... I had some left over empty ones so I re-filled them and sent some over to Obsidian and Bethesda as thanks for the upcoming Fallout: New Vegas.

As far as the manufacture: after quite a bit of searching I found some blank tins, then very carefully measured the box to make sure the labeling would fit just right. As far as the design of the labels I went with a combination between the look of Mentats in Fallout 2 and in Fallout 3. I did all the illustrations and layout in Adobe Illustrator (all vector artwork). I printed them out, ran them through a decaller (laminates one side and makes the other side sticky), and carefully placed them on the tins. The bottom wrap around label is one giant piece that sticks to itself, so you have to make that just right. The decaller I have access to doesn't do a very good job of sticking to metals, so I had to do a few tricks like that one to ensure everything would stay in place. For the mentats themselves I used Spree, since they most resembled Mentats. The wife and and I had to go through a ton of theatre-sized boxes of Spree, separating the red, purple, and orange ones by hand (with gloves). We even added hand-cut green-foam inserts between each layer of candy so the layers wouldn't get damaged and everything stayed in place. So there you go, probably way more information than you wanted .
